Stochastic simulation of the micro-meso transition in the evolution process of defective structure in loaded high-strength material

Based on synergetic principles and statistical approach, mathematical modeling of the micro-meso transition in microdefects accumulation process in loaded high-strength material has been performed. The stochastic model of submicrocracks system evolution in the material at micro level has been constructed. The computational experiment has been performed for the case of uniaxial plastic deformation of structural steel 30HGSA. Calculated submicrocracks density curves for different degree of the system non-additivity, characterizing the material structure ordering degree, have been presented and analyzed.
